To all whom it may concern.- Be it known that I, WILLIAM FRANKLINILAYTON, a citizen of the United States, residing at Atlanta, in thecounty of Fulton and State of. Georgia, have invented-certain new anduseful Improvements in Thin-Place the following to best full, clear, andexact deable others skilled in the art to which it appertains to makeand use the same.

My invention relates to looms, and it is more particularly anattachmentfor autotle does not work or the filling misses one or picksand when a thin or imperfect place is therefore produced within thefabric.

The invention consists of the novel features of-construction andcombination of parts which will be hereinafter more fully describ ed,and pointed out in the claims.

In the 4 accompanying drawings. I have shown the preferred formsofmyinventiong- Fi ure 1 is a perspective view of a portion of a oom,showing my improved attachment thereon. Fig. 2 is a detail view showingthe means for connecting the dog to the knock-off Fig. 3 is a View,partly in elevation and partly in section, showing a portion of amodified form of attachment.

Referring to the figures by numerals of reference, 1 is the breast-beamof aloom, the same having brackets 2 thereon, in which is rotatablymounted a detector-rod 3. A11

is adapted to contact with the fabric 6 in the loom at about two picksfrom the shuttle. Another arm 7 extends through and loosely engages anarm 8, which extends laterally from a latch-bar 9. This latch-bar isconnected by a loop 10 with the knock-off lever 1 1 of the loom and isadapted to fall into engagement hammer hook 12, mounted on theweft-hammer12.

It will be understood that as the woven will be supported thereb alwaysat about two picks from the shutt e; but should said shuttle fail towork or should the filler miss one or more pickaand a thin or-openportion i Specification of Letters Patent.

be therefore produced in the fabric, the finger 5 would drop as soon assaid thin portion arrives in position'thereunder, and therefore causearm 7 to 'swingdownward'and allow the latch-bar 9 to fall intoengagement with the notchintheweft-hammerhook12; With this attachmentthe mechanism of the loom will therefore be promptly stopped when a thinplace is produced in the woven fabric.

It will also be understood that, as shown in Fig. 3, the detector-rod 3can. be 'rotatably mounted within a sleeve 17. This sleeve is desiredtofasten the attachment to the te'mplet, under which cir-- y cumstancesthe templet is swung backward and the sleeve 17 clamped within the loopthereof. I T v WhatIclaimis' 1. In a mechanism of theclassdescribed, thecombination with theknock-off lever, of a upon the rod, a latch-barsupported by the arm and pivoted to the knock-off lever provided with, aprojection, a weft-hammer, and a weft hammer hook adapted .to engage theprojection when. the hammer advances; v

2. In a mechanism of theclass. described, 8 the combination with thew'kn'ock-ofi lever, hammer, and weft-hammer hook, of a piv oteddetector-rod, a latch-bar pivoted to the knock-off lever provided with aproj ection in the line'of travel of the hammer-hook, and means uponthedetector-rod for normally, supporting the latch-bar out of engagementwith said hook.

3. Ina mechanism of the class described,

the combination-with the kngck 'oii lever, weft-hammer, and hammer-hook,of a p1v oted'detector-rod, a latch-rod pivoted to the knock-ofl leverhaving a projection adapted to engage the hammer-hook, and an 'arm uponthe detector-rod for normally keeping the latch-bar outof engagementwith the hammer-hook. I I 4, In a mechanism-of the class described, thecombination with the knock-off lever, weft-hammer, and hammenhook, of apivoted detector-rod, .a finger upon. the rod adaptedv to rest upon thecloth, an arm upon, the rod, a latch-bar provided with a projec tionsupported by the arm above the hammer-hook, when the finger is restingupon the I 0 5 cloth, and permitting the projection to engage thehammer-hook when the finger descends, and pivoted connectionsbetween thebar supported by the arm and a weft-hamshipper-lever and latch-bar.

5. A detector-rod mounted with its point upon the cloth and having anextension, a knock-off lever and wer't-hammer, a latchbar connectingwith the knock-off lever and supported by said extension to engage theWeft -hammer when the pointenters the cloth.

6. A pivotally-mounted detector-rod hav-. ing a cloth-engaging point andan extension, a weft-hammer, "a latch-bar supported by said extensionabove said hammer and means to utilize the movement of the latch-barwhen the latter is struck by the weft-hammer incident to the pointentering the cloth.

7. The combination with the knock-0H 1ever of a detector-rod having anarm, a latchmer designed to'cause the latch-bar to operate theknock-ofl' lever.

8. They combination with the knock-off 1ever; of a pivoted detector-rod,an arm upon the rod, a latch bar su ported by the arm and connected.with. the nock-ofi' lever and. a weft-hammerdesigned to engage theiatchbar and operate the knock-off lever.

9. The combination with the knoek-ofl' iever and weft-hammer; of adetector-rod, a

latch-bar connecting with the knock-off lever and means upon thedetector-rod for normaily supporting the latch-bar out of engagementwith the weft-hammer.

107 The combination with the knock-ofi lea ver,wveft-hammer andhammer-hook; of a detector-rod, a latch-bar connecting with theknock-off lever and having a projection designed to be engaged by thehammer-hook, an arm upon the detector-rod adapted to normally supportthe latch-bar out of en gagement with the hammer-hook.

' 11. The combination with the knock-off-lever and weft-hammer; of apivoted detectorrod, a finger upon the rod to rest upon the cloth, anarm upon the rod, a latch-bar supported by the arm out of the path ofthe weft hammer when the finger is resting on the cloth whereby thelatch-bar will moveinto engagement with the weft-hammer when the fingerpasses'through the cloth.

I In. testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
